ABSTRACT Purpose:To evaluate the effects of hydroalcoholic extract of Passiflora edulis leaves in the healing of urinary bladder in rats from histological aspects. Methods: Forty Wistar male rats were submitted to a longitudinal incision of the bladder followed by a stetching in only one level. After this common procedure, animals were divided at random two groups: Passiflora and Control. In the Passiflora group the only dosage used was administered by intraperitonial injection of hydoalcoholic extract of Passiflora edulis leaves while in the Control group distilled water was injected. Each subgroup was then divided in two subgroups according to the death of these animals: Control, three and seven days, Passiflora, three and seven days. After the death of these animals, an inventory of the abdominal cavity was performed and the bladder was removed. A comparative analysis was done between the two groups with microscopic evaluation of the healing. There was less acute inflammation (p=0.008), greater colagenous formation (p=0.001) and greater capillary neo-formation (p=0.000) in the third day Passiflora subgroup when compared to the Control subgroup of the third day. Results: There was less acute inflammation (p=0.001), greater fibroblastic proliferation (p=0.011) and greater colagenous formation (p=0.001) in the Passiflora subgroup of seventh day when compared with the Control seventh day subgroup. Conclusion: The use of Passiflora edulis leaves extract resulted in less acute inflammation, greater fibroblastic proliferation, colagenous formation and capillary neo-formation on rats bladder wound healing. Key words: Passiflora edulis. Wound Healing. Bladder. Rats.
IntroduçãoA cicatrização é um processo que visa limitar os danos e restabelecer a integridade e a função dos tecidos afetados 1 .Os avanços da biologia celular e molecular têm permitido o estudo e ampliado o conhecimento das etapas da cicatrização. Sabe-se que os tecidos cicatrizam-se de maneira
Ileal inflammatory fibroid polyp is a rare non-neoplastic lesion of the gastrointestinal tract. Intussusception caused by an inflammatory fibroid polyps is uncommon. The authors report a case of a 75 year-old female patient presenting with ileal obstruction due to intussusception of a polypoid lesion. The patient underwent surgical treatment and histopathology confirmed the diagnosis.
OBJETIVO: Avaliar os efeitos da castração pós-natal sobre o tecido pulmonar na sepse de origem abdominal induzida em ratos. MÉTODOS: Foram utilizados 33 ratos Wistar distribuídos em dois grupos: Grupo Controle (GC) = 5 machos adultos normais sem desafio séptico. Grupo Experimento (GE): 28 ratos submetidos a sepse por ligadura e perfuração de ceco (LPC) e distribuídos em três subgrupos: Subgrupo Macho (SgM): nove ratos machos adultos, sem castracão e submetidos a sepse por LPC. Subgrupo Fêmea (SgF): nove ratos fêmeas adultos normais submetidas a sepse por LPC. Subgrupo Castrado (SgC): dez ratos machos que no quarto dia de vida foram submetidos a orquiectomia bilateral e quando adultos à sepse por LPC. Após a LPC os animais foram observados até o óbito, realizada análise histomorfométrica do pulmão, observando-se o número de polimorfonucleares e mononucleares. RESULTADOS: 50% dos animais do SgC sobreviveram 24 horas, contra 33% do SgF e 0% do SgM, mostrando uma nítida influência da castração na resposta ao desafio séptico. O número de polimorfonucleares e mononucleares não foi diferente estatisticamente entre o SgC e CG, estando estatisticamente aumentados no SgM e SgF. CONCLUSÃO: Os animais castrados apresentaram uma maior tendência à sobrevida e menor alteração pulmonar.
Data suggest a better survival to sepsis within 24 hours for the F and CM groups, the presence or absence of testosterone in early periods of post-natal life being responsible for these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
